The Patagonia Velocity Cap is your get sweaty, get muddy and get tired running hat. It has built-in breathability with panels and a crown that's made from Air Flow mesh to deflect heat. The 5-panel design allows a close fit that slices through persistent headwinds and is customized with an elasticized buckle closure. A wicking Coolmax headband keeps sweat out of your eyes, and a dark underbill shades them from glare.
